Is it possible to create a Bitcoin URI with multiple outputs?

Question

The Bitcoin URI scheme allows for the creation of single-click payment request, using the format

bitcoin:<address>&amount=<amount>

such as

bitcoin:1AzGoMQfrQ7fYaE12dAvEVkke8111rxwCm&amount=0.01

Does the URI scheme also allow multiple payments to multiple destination addresses?

Answer 1

No, this is not possible according to BIP 0021. The BNF grammar for the bitcoin: URI scheme starts with:

bitcoinurn     = "bitcoin:" bitcoinaddress [ "?" bitcoinparams ]

Since bitcoinparams has no address information, this means that exactly one output address is required.
